Onkyo TX-SR607

If 7.1 surround sound wasn't enough, Onkyo is serving up a new receiver that's capable of 7.2 channels of sound via Dolby's new Pro Logic IIz mode. What the new mode offers over 7.1 is the ability to create sound effects over your head (like a plane flying over) using left and right front speakers mounted on top of your main speakers. The receiver also features support for all the latest audio processing formats, 1080i upconversion, and a wide array of HDMI, component, and various other outputs. Link: $600 / Source
